"Baldur's Gate 3: Mastering the Art of Romancing Karlach in BG3"
To romance Karlach in Baldur's Gate 3, players must earn her favor in Act I by siding with the Tieflings at Druid Grove and helping them, as well as wiping out the Goblin Camp. To fully romance her, players need to find the Infernal Mechanic named Dammon and collect Infernal Iron. Dammon can be found at Druid Grove and later at the Last Light Inn. Infernal Iron can be found in the Goblin Camp, the Mason's Guild in the Shadowlands, or the Temple of Shar. Once the pieces are brought to Dammon, players have a small window to kiss Karlach as her skin cools down, and the romance can continue with the use of water, ice, and more Infernal Iron.
